Greetings AB,

That would be perfect...appreciate your effort.

I do believe that we could gain something out of this ;-)

I do expect a different effect. If I am correct I see the ball falling down causing the rocking action to happen. Then as it rolls it will rock back quickly do to the energy rolling and then lifting up on the other end causing the ball to go off the other end. What I expect here is the rocking action to be lower than the start when the ball goes off. On the one you show I will have to get something to hold it on the upper rocking action. Just thinking about such a simple device opens several sub test to be done as well.

Two more views.

AB...

Let me try to make a quick animation to prevent misunderstandings...

– the ball fall
– the egg-curve rock (down) to the right
– and lifting the left side of the egg-curve up (once)
– giving an impact and at the same time
– it is catched or locked

Well Ruggero...

The curvature the weight follows in Abeling's device isn't a circle so the G-max, as you call it, is far more spread out over a "stretch" rather than occurring at some single point in it. That naturally enough increases the distance the weight can travel under it's own steam by using some of that same gravity to do it.

It goes on to a very big backward "C" circle shape at 1 o'clock and then off it before 5 into a slightly downward and then lateral path before heading sharply up and into a much smaller "c" shaped hairpin turn to move more laterally once again back to it's beginning.

So it's an eliptical path if anything, like an egg lying on it's side and the widest end being on the wheel. The bottom area where you'd look for that g-max point is actually even more flattened out than that and would spread the gravity as is the corresponding top part in doing the same for it's return.

[ruggerodk]

Silverfox,

That was a good explanation.

Though I have to ask you – to be sure that I understand you right:

– Does the ball USE the G-force (max position)to roll forward and climbing?
(for clearness, lets stay with the 'normal' round shape sphere)

– Does the ball loose velocity without the G-force (max position)?

– A spring pendulum will not gain more height, with or without the spring.
Without the spring I believe the G-force only increase the pendulum's tension on the axle (drag)?

What I mean is:
The gravity from the falling ball (01:00 to 06:00) makes the wheel go round.
But after 06:00 I can only imagine this gravity force is slowing down both the ball's rolling (and the wheel's rotation)...am I right?

My suggestion is to take away this 'drag and tension' ...and use it for something else (like an impact to shoot the weight at 11:00 over the top).

OK Hammer and Silverfox

I have made some new drawings, from a quick model build (cardboard).

When the ball (A) is dropped either on a fixed/steady 180 dgr circle curve (left image – red curve), or on a rocking 180 dgr circle curve (left image – red rocking to green and locked at 11:00), the ball end up at same height (B)..!!!

This tells me there are gravity force (or push-down force) at 06:00 that can be used for other purposes.

Perhaps helping another ball over the top...?

[silverfox]

Now you're getting closer, Ruggero, but obviously you can see that the point where the circles meet must be far more rounded out if there is to be a smooth transition from one to the other for your little green ball.

You're going to have to cut a good chunk of that bottom travel out of both of them and create the most ideal curve for that job. If you do it right you can kill several birds with one stone, so to speak.

So without further ado...

repeat after me...

Prest-O....

Change-O...

Fibonacci!

If you don't know what what a Fibonacci spiral looks like just google one.
The connection for the two circles will be immediately obvious once you do. So too should be the advantages.

Now leading into the heart of a Fibonacci curve will concentrate the speed and momentum as it steadily reduces the distance so there should be centrifical force built up for a hook shot right into the basket if we have enough going in.

[ruggerodk]

Thank you for your comments, Silverfox.

Fibonacci is definately worth a thought, and I have been studying on his curves for ball-wheels etc.

What several people have noticed in here, is that there are no precise calculations of he torque, g-force, drag, push, velocity, acceleration...you name it...on spirals and spiral ramps!

Back to my 'egg-rocker':
You got my drawing wrong.
The red and green ramps are one and the same ramp illustrating start and end positions.

I have made some quick video's of three different setups:

1) a free rocking ramp
2) a free rocking ramp, that are catched and fixed in its upmost rocking position
3) a totally fixed half-circle ramp

The perspective makes it hard to see the ball position, but I can assure you that all three end positions are the same...! (+/- 3 mm)

The video's can be seen here:

Larger weights have a slightly different reaction. It is the difference between the mass of the weight and the mass of the rocker. But no difference on a stationary track.

[erick]

This (the Avalanche Design) design could be vastly simplified by making the parallel tracks on one side of the unit closer together than the other side. The fact that they're closer together will force the weights to "spread out" more on that side as compared to the other, theoretically resulting in an imbalance.

I foresee that gear mechanism (or whatever it is) causing you lots of headaches.

I've seen 'em a lot of times.
What in particular do you want me to notice?

Apart from that, Dusty – and many others – are overlooking a major item/mechanisme from Abeling's photo:

Look at the green 'thing' on this overlay drawing: What is that for?

If you follow the ramp-track on Abeling's wheel, according to his photo the weight will smash into that green mechanisme! It's in the way...and how do you pass it?

And more:
Just right of this mechanisme you see another slightly tipped piece of lightwood, almost like hanging from 12:00 or 01:00.
What is that for?

And again:
The ramp is supported at the buttom by some extra curved plywood, between the column and the ramp.
What is that for?
Most unlikely a support for the ramp.

I believe there to be two ramps:
One fixed and one rocking (or sliding).
The rocking ramp will be connected to the green mechanisme between 09:00 and 12:00.
(see drawing)
